CONTROLLER-SWITCH.

Specification of Letters Patent.

Patented Aug. 19,1 913.

To all whom it may concern Be it known that I, VINCENT Gr. Arrnn, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Controller- Switches, of which the following is a specification.

My invention relates to improvements in controller switches for controlling the circuits of a dynamo electric machine and especially the relation of' a dynamo electric machine with a storage battery.

One of the objects of my invention is to provide a switch, of the character to be hereinafter described, that is particularly well designed and adapted to be used in connection with a storagebattery, and a dynamo electric machine, whereby said battery may be connected in series relation with said dynamo, when using the dynamo as a motor, and in parallel relation with said dynamo electric machine when using said dynamo as a generator.

One of the particular objects of my invention is to provide a switch of the general character heretofore'referred to which is especially adapted to be used in connection with a dynamo and storage batteries for starting an internal combustion engine employed for propelling automobiles, and for subsequently arranging the circuits so that the dynamo may be made properly to charge the said batteries when the engine becomes self propelling.

Other and further and more specific objccts of my invention will be readily understood by persons skilled in the art from a consideration of the following descriptionwhen taken in conjunction with the drawings, wherein Figure 1 is a front elevation of my controller switch with the cover removed; Fig. 2 is a rear elevation of the same showing the terminal binding posts for connection to the various circuits; Fig. 3 is a rear elevation showing the outer terminal board removed and showing some of the internal connections between the various parts of the said contro1ler; Fig. 4 is a lan view of the controller showing the switch lever in off position; Fig. 5 is a cross sectional view taken on line 55 of Fig. 1, showing the top member of the frame and looking in the direction or the arrows; Flg. 6 is a transverse sectional view taken on line 66 of Fig. 1 looking in the direction of the arrows; Fig. 7 is a fragmentary view looking from the bottom toward the top of the rocking, switch element, containing a series of switch blades adapted to make electrical contact with the respective stationary clips, of the controller switch; Fig. "l' is a side view of two of the clips and respective blades; Fig. 8 is a transverse view of the lighting controlling switch taken on line 88 of Fig. 1; Figs. 9, 10, 11 and 12, are cross sectional views showing the various positions of the rocking switch element and the respective switch blades with reference to their respective coacting stationary clips; Fig. 13 is a central vertical section of the controller showing a part of the cover therefor in place; Fig. 14 is a transverse section takenon line 1414 of Fig.1; Fig. 15 is a similar section taken on line 1515 of Fig. 1'; Fig. 16 is a diagram of electric circuits connecting-the dynamo electric machine and the batteries and diagrammatically including my present circuit controller.

In all the views the same reference characters are used to indicate similar parts.

' The frame upon which the device is constructed includes two major portions. 200 is the rear wall of the major port-ion provided with a forwardly extending bottomportion 201, and a separable upper portion 202 provided with a top forward extension 203 and a rear extension 204. The top porti'on 203 is provided, near its front limit with a downwardly extending flange 205. The frame could be made of a single integral'piece, if desired, but I prefer to make it in two parts for convenience of structure, and for lightness I have made. them of aluminum castings.

Mounted on the front wall of the frame and'extending upwardly to a point approximating the parts 202, is a plate of insulating materialgQOG. Another plate of insulating material 207 is also mounted on the front of the wall 200, upon which to mountthe of electrical distribution filed by terminals of the lighting switch, which may frame and serves as a protecting means to prevent accidental displacement of the switch handle bar which'is employed to operate the moving elements of the controller. This upper portion of the frame is reinforced as at 209, 210 and 211, to provide receiving means for devices that are operable from the outer, and top portion of the controller.

In a copending application for a system me on the 22nd day of July, 1912,.and identified by Serial No. 710,864, I have shown a system which is adapted to be carried into effect by the operation of the present controller, and in Fig. 16 of this case I have shown a diagram of circuits as they are presented in the aforesaid system case, the parts thereof being indicated by the same reference characters as those used in the former case, and in this case I have indicated the same parts with corresponding reference characters.

The rocking switch element of the controller, comprising a series of switch blades is shown in F ig.-7 and these parts are indicated and have the same office as similar parts shown in diagrammatic relation in Fig.16.

' =A rotatable shaft 212 is supported in the frame 200 in bearings afforded by the flanges 201 and 203. It extends through the upper flange or plate 203 and is provided on this end with an indicating turning button 213, secured to the shaft by means of a pin 214. The button is pointed as at 215, more clearly shown in Fig. 4, which point serves as an indicator for showing the position of the shaft, and attached parts when they are rotated by means of the button. The specific object and function of which will be hereinafter more fully explained.

Mounted on the shaft 212 is a sleeve of insulating material 216, which is adaptedto be freely rotated on the shaft by means of a handle 217 which is secured thereto and which terminates in a finger piece 218. The insulating sleeve 216, is longitudinally grooved, as at 219 and 220, and each of the switch blades is provided with an inwardly extending lug 221 for engaging either one or the other of the said grooves. For purpose of convenience of construction the blades of equal length are made in duplicates so that when the blades are either turned to the left or the right in assembling them on the sleeve, the projection 221 is adapted to enter either of the grooves 219 and 220 as the case may be and thereby the blades are secured on the sleeve to prevent relative rotat ion thereon.

On the shaft 212 is another sleeve 223, of insulating material, secured thereto by means of a pin 224;, against this fixed sleeve the rotatable sleeve 216 of the controller abuts. A ratchet wheel 225 is provided with 6 teeth and corresponding depressions, and is secured to the shaft 212 by means of a pin 226. This ratchet wheel is provided with 6 teeth 228 and is resistingly held in the position to which it has been moved by the thumb button 213 by means of a spring pawl 227, so that the shaft 212 will be yieldingly retained in the position to which it has been placed for the purpose of operating the lighting switch.

The lighting switch, which is to be hereinafter described is operable quite independ- 8' ently of the controller switch, as the contacts thereof may be readily moved by turning the shaft 212, by meansof the button 213, without disturbing the. contact relation ofthe controller mechanism mounted upon the 9( rotatable insulating sleeve 216.

In the construction of the controller switch, washers 229 and 230 are first. mount- I ed upon the insulating sleeve 216 and se- Then an 9% cured thereto by proper means. insulating disk 231 is slipped over the sleeve and placed adjacent to washer 229 then one" of the long blades of the switch controller, 108, is placed over the insulating sleeve having its projection 221 projecting into the 14 groove 220, so as to hold the blade on the sleeve and prevent rotation. Each of the blades is provided with a radial projection as at 232 into which connecting wires such as 52, 53, and 57 may be soldered for the 11 purpose of connecting the respective blades together, as shown in Figs. 7 and 16. It will be observed, by referring to Fig. 13 that a metallic washer 52 is placed between the blades '50 and 108 for the purpose of connect- 1 ing them together. After the blade 52. has been placed in position on the insulating sleeve, a spacing washer 232 is threaded over the sleeve and put incontact with an insur lating washer 231 and in' this manner the 1 entire mechanism, composing the oscillating element of the controlling device, is built up. After the last spacing ring 232 is placed over the sleeve, a washer 233 is placed over the reduced end of the insulating sleeve to hold 1 the parts in assembled position and the switch moving lever 217 is then secured to the washer 233, and to the sleeve 216, by proper means, so that the assembled mechanism thereof lever 217 is moved laterally.

Looking at Fig. 1 it will be observed that the switch blades of the oscillatable mechamay be oscillated when the 1 .plate of insulating material 239, is placed taining th interior connections, and other ,means of'which the terminal circuit conthe right, as shown in Fig. 10, and the,

nism, on the left hand side, indicated by the following reference characters in consecutive order, beginning at the top and ending at the bottom; 16, 18, 21, 23, 26, 28, 31, 33, 36, 38, 60, and 50, and the blades on th'e right hand side of the axis, are indicated by reference characters; 95, 96, 98, 91, 101, 89, 104, 87, 106, 85, 107, and 108, and that the respective cooperating stationary switch clips are indicated by a, a, b, b, c, c, d, d, e, e f, and f, and those on the left hand side are indicated by the reference characters m, n, 0, p:ga 7 7 7 a I Q The construction of the switch clips is clearly shown in Fig. 7 wherein a single strip of spring copper or the like is bent upon itself having its ends inturn'ed to form frictional contact surfaces for the respective blades. In this figure it will be shown that blade 60 when moving downwardly, severs its connect-ion with its clips, while all of the other blades of the device sever their electrical connections with their respective clips when the blades are moved upwardly.

The clips are placed in grooves 236 made in the insulating plate 206 and are held in position by means of screws 237 which pass through perforations made in the base of the clips. The plate 200 is perforated for each of the screws and the perforations or holes, are insulated .by bushings 238. I A

over the bottom surface of the metal plate 200 to afford insulation therefor and the bushings 238 pass through the plates 206 and 239 as well as the plate of the main supporting frame 200.

All of the connections between thevarious screws on the back of the device are made as shown in Fig. 3, before the final plate 240 f is placed in position and all of the screws that pass through this latter plate afior'd terminal binding posts for exterior circuit connections as shown in Fig. 2. 'The plate 240 serves as a protection for the interior connect-ions that are contained between the plates 239 and 240. Screw nuts 241, serve to hold the screws in place and also' serve as distance spacing means to hold the plates 239 and 24 apart to provide space for connuts 242, -takin over the screws 237 serve as check nuts t hold the late 240 in place and to prevent turning of t e screws. O ther nuts are provided for the screws 237 by necting wires are secured tothe said terminal screws. c I

When the moving member of thcontrolling switch, containing the switch blades, is rotated upon its axis, or the shaft 212', to

switch blades on the left hand side, as shown in Fig. 1 are brought into contact with their respective switch clips, the storage batteries, with which the device is adapted to be used, in connection with the dynamo electric machine have all of the cells of which the batteries are composed connected in series relation with each other, and the highest electromotive force, of which the battery is capable, is expressed at the terminals of such 'connection and the battery so arranged, is

this transit movement, as shown in Fig. 9

where none of the switch blades are making contact with their respective clips. When the switch moving element is oscillated further, in the direction shown in Fig. 11,

the blades make contact as shown in Fig. 12, with their respective clips and the batteries are connected in parallel relation with each other and with the dynamo, in condition for charging by the dynamo when the driving engine becomes' self propelling.

A lock plate 243, is secured to the part 202, by means'of screws 244. It is provided wit-h a down turned flange 245. The flange is tapered toward each extremity from the intermediate notch 246. The switch moving lever 217, has 'sufiicient spring tension to cause it to snap into the notch 246 when it is moved across the flange 245.. When the lever is in the notch the oscillating switch element is in the position as shown in Fig. 11. That is to say, that all of the blades on the right hand side of the axis of the moving element, as shown in Fig. 1 make contact with their respective clips, with exception of blades 107 and 108, and by this latter means the igniting circuit, for the internal combustion engine is broken, butt-he lighting circuits for maintaining the lamps lighted, as will main closed.

When the handle 218 of the lever 217 is moved to the position shown'in dotted lines and marked S in Fi 4, which signifies be hereafter"explained, re-

" starting position the parts of the con-,

troller are in position shown in Fig. 10, wherein the batteries are connected in eries relation with each other and with the dynamo, and the dynamo is in condition to operate as a motor for starting said engine. After the engine has become self propelling it becomes desirable to connect the batteries in parallel relation, and this may be done by quickly moving the lever 217 from the position shown in dotted lines the lever 217 in off position for locking the inclosing casing 273 and for locking the a shaft 212 so that it cannot be rotated until time the projection 248, of the locking plate the device has been unlocked. The plate 248 is moved in the opposite direction to that in which it has been moved by means of the key, by a spring 250. The plate is provided with two guiding slots 251, in which screws 252 prevent the lateral movement of the plate 248. The locking plate 248, is provided with downturned lugs 253, 254 and 255. The lug 253 engages the notches between the teeth 228, of the ratchet wheel 225, so as to prevent the rotation of the lighting switch, and the shaft 212, when the plate 248 is in locked position, at which 248, engages the locking tongue 277 and prevents turning of the button 276 and thus the casing, or cover 273 may not be removed when the key is turned to move the locking plate 248 to locking position. The lever 217 is provided with an upturned lug 256, shown in Fig. 14, which is contained between-the lugs 254 and 255 of the locking plate, at the time when the locking plate is moved to locked position and when the lever 217 is in the notch 246. By this means the moving parts of the controlling device are locked against unauthorized use, and when the parts are in this position the engine cannot be started because the igniting circuit is open. When the key is turned to unlocking position the plate 248 is immediately moved to corresponding position by means of the spring 250 and the lugs 253, 254 and 255, are withdrawn from engagement with the moving instrumentalities leaving them free to be moved for performing their res ective and intended functions.

The lightlng switch, or the switch by means of which the electric lights of an automobile, for instance, are controlled, is mounted on the insulating sleeve 223 which is secured to the extending end of shaft 212. Contact plates 160, 161 and 162, are secured on this sleeve and are shown protracted in diagram Fig. 16, and the connections that are effected by the'rotation of these arts, as'when the shaft 212 is turned, is c early disclosed in this figure and they are more specifically explained in my copending application for a system of electrical distribution to which I have heretofore referred.

From the foregoing description it will be obvious that the lighting switch is operable quite independently of that portion of the switch constituting the control for the dynamo and for the storage batteries, and that both operating instrumentalities are capable of being locked in given positions by means of the same lock and key.

The spring pressed coacting switch terminals, for the rotating ortion of the light ing switch are indicate by112, 113, 125, 138, 141 and 142. These contact members are relatively stationary and have frictional yielding'bearing upon the rotatable contact members. They are placed in grooves,in the insulating base plate 207 and are held in positions by means of screws 260 which pass through the lates 200, 239 and 240 just as the screws 23 are employed to support the clips of the motor controller, and as clearly shown in Fig. 8.

Safety fuse devices 261 and 262, also indicated by M F, and L F, respectively, are mounted upon post, orpillars 263, of which there are three pillars supporting the terminals of the respective fuses that are secured thereto by screws 264. Screws 265, have engagement with the terminal posts 263, for connection of electric circuits, and these posts are secured to the base 200, by means of bolts 266 taking through the said base plates and insulated therefrom.

An electro magnetic relay 267, serves as an automatic means for cutting the dynamo into circuit with the storage batteries at the time when the electromotive force, due to the speed of the dynamo, equals or exceeds, that of the batteries. An electro magnetic relay 268, serves as a means for decreasing the electromotive force, at a given speed of the dynamo, when the storage batteries have been partially or completely charged thereby automatically decreasing the current supplied to the storage batteries when they, no longer require the -full current that can be produced by the dynamo.

The function and operation of these magnetic relays are fully disclosed and claimed 'n my copending application for electrical distribution systems, to-which I have heretofore referred,

A test light 269 is mounted on the upper part of the casing and is ca able of bemg placed in circuit by means'of a switch 270. While this'-;indicates the relative condition of the dynamo electric'machine and storage batteries, at the same time it serves to illuminate the top of the casing so that the key may be readily inserted in the lock, for instance, or the button 213, of the lighting switch may be rotated to the desired posir tion indicated by the scale on top of the casing. A similar switch 271, may be used for lighting the electric lamp usually placed on the dash board of an automobile and it is so arranged that the light will continue to burn as long as the switch has been placed in the desired posit-ion to which it has been The slots also permit the entire removal of the casing, when desired.

A latch 276 is provided with aelocking tongue 277 'that engages a projection 278- on the frame'part 203.

The general use and operation of the device will be apparent from the foregoing description.
